Večfunkcijsko svetilo motornega vozilaMotor vehicle multifunction lamp

Izum spada na področje vozil oz. svetlobne in signalizacij ske opreme za vozila, še zlasti prednjih žarometov in meglenk, konkretno pa se nanaša na svetilo, ki je poleg osvetljevanja območja pred vozilom predvideno tudi za osvetljevanje drugih območij, namreč za takoimenovano večfunkcijsko svetilo, ki je zmožno bodisi sočasno ali vsaj občasno vršiti različne funkcije in torej lahko služi kot prednji žaromet, z integrirano dolgo lučjo in/ali kratko lučjo in/ali parkirno lučjo in/ali smernim kazalcem in/ali kotno lučjo, ali pa npr. kot meglenka z integrirano kotno lučjo, ali podobno.The invention falls within the field of vehicles or vehicles. lighting and signaling equipment for vehicles, in particular the headlamps and fog lamps, and in particular refers to a lamp which, in addition to illuminating the area in front of the vehicle, is intended to illuminate other areas, namely a so-called multifunctional lamp capable of either simultaneous or at least occasional perform different functions and can therefore serve as a headlamp, with integrated high beam and / or dipped beam and / or parking lamp and / or direction indicator and / or angle lamp, or e.g. as a fog lamp with integrated corner light, or the like.

Pri tem izum temelji na problemu, kako zasnovati večfunkcijsko svetilo motornega vozila, pri katerem bo glede na vsakokratno število svetilnih funkcij v primerjavi z znanimi svetili število sestavnih delov manjše, s čimer bo poleg nižjih stroškov izdelave tudi verjetnost okvar manjša.The invention is based on the problem of designing a multifunctional motor vehicle light in which the number of components in comparison with the known number of lighting functions is lower than the known lights, thus reducing the likelihood of failures in addition to lower manufacturing costs.

Prijavitelju so znana različna večfunkcijska svetila pri motornih vozilih, ki so zmožna po izbiri, lahko tudi sočasno, vršiti več svetilnih različnih funkcij, npr. funkcijo kratke ali dolge luči, smernega kazalca, dnevne luči, kotne luči ali podobno. Za znane tovrstne rešitve je značilno, da je vsak svetlobni vir, ki je predviden za izvajanje določene funkcije, električno napajan iz lastnega izvora električne energije, ki je še zlasti enokanalni DC/DC konverter. Svetlobni vir za izvajanje določene svetilne funkcije je bodisi žarnica z žarilno nitko, še zlasti halogenska žarnica, ali pa svetleča dioda (LED) oziroma niz med seboj v ustrezen tokokrog električno povezanih LED. Vgradnja vsakega izmed električnih virov, ki so predvideni za napajanje vsakega izmed vsakokrat razpoložljivih svetlobnega virov, je povezana z določenimi stroški, obenem pa večje število sestavnih delov pomeni tudi večjo verjetnost okvar.The Applicant is aware of the various multifunctional lamps for motor vehicles that are capable of optional, simultaneous, multiple lighting functions, e.g. low beam or high beam function, direction indicator, daylight, corner light or the like. Known solutions of this type are that each light source intended to perform a particular function is electrically powered from its own power source, in particular a single-channel DC / DC converter. The light source for performing a given luminous function is either a filament lamp, in particular a halogen lamp, or a light emitting diode (LED) or a series of interconnected circuits into an electrically connected LED circuit. The installation of each of the electrical sources intended to power each of the available light sources is associated with a certain cost, but at the same time a greater number of components means a greater likelihood of failure.

Izum v osnovi temelji na zamisli, da bi bilo možno vsakokrat razpoložljive svetlobne vire za izvajanje različnih svetilnih funkcij električno napajati iz enega samega vira električne energije, pri čemer naj bi bil vsakokraten svetlobni vir zmožen opravljati svojo funkcijo neodvisno od delovanja preostalih svetlobnih virov in tudi v primeru motenj pri delovanju katerega izmed svetlobnih virov, napajanih iz omenjenega skupnega vira električne energije. S tem bi se število sestavnih delov svetila zmanjšalo, svetilo bi bilo možno izdelati z nižjimi stroški, obenem pa bi bila tudi verjetnost okvar manjša.The invention is basically based on the idea that the available light sources for performing various lighting functions could be electrically powered from a single power source, whereby each light source would be able to perform its function independently of the operation of the remaining light sources and also in in the event of a malfunction of any of the light sources supplied from said common source of electricity. This would reduce the number of components of the luminaire, make the luminaire at a lower cost, while reducing the likelihood of failure.

Izum se torej v splošnem nanaša na večfunkcijsko svetilo motornega vozila, pri čemer tovrstno svetilo obsega vsaj dva v ustreznem ohišju svetila vgrajena, pred zunanjimi vplivi zaščitena in po izbiri za sodelovanje z vsakokrat razpoložljivim reflektorjem in/ali lečo prirejena svetlobna vira, izmed katerih je vsak predviden za izvajanje vnaprej določene svetilne funkcije, in sicer vsakokrat neodvisno od izvajanja svetilnih funkcij s strani vsakokrat preostalih svetlobnih virov, in pri čemer je za krmiljenje omenjenih svetilnih funkcij vsakokrat razpoložljivih svetlobnih virov predvidena vsaj ena krmilna enota s pripadajočim DC-DC konvertorjem, od katere je odvisno napajanje vsakega izmed vsakokrat razpoložljivih svetlobnih virov z električno energijo iz vsakokrat pripadajočega vira električne energije.The invention therefore generally relates to a multipurpose motor vehicle light, such light comprising at least two lamps fitted in an appropriate housing, protected from external influences and optionally adapted to cooperate with a reflector and / or lens available at all times, each of which is a light source. provided for the predetermined luminous function, in each case independently of the luminaire function by the remaining light sources, and wherein at least one control unit with an associated DC-DC converter is provided to control said luminous functions of the light sources available at each time depends on the supply of each of the available light sources with electricity from the respective source of electricity.

Pri večfunkcijskem svetilu po izumu je predvideno, da je vsak izmed vsakokrat razpoložljivih svetlobnih virov električno povezan v poseben, zgolj njemu lasten sekundami električni tokokrog, v katerem je poleg omenjenega svetlobnega vira vsakokrat vgrajen tudi električni prekinjevalni sklop, pri čemer so vsi vsakokrat razpoložljivi sekundami tokokrogi zaporedno električno povezani v primarni električni tokokrog, v katerem je vključen en sam in vsem sekundarnim tokokrogom in torej tudi vsem vsakokrat razpoložljivim svetlobnim virom skupen enokanalni DC-DC-konvertor, s katerim električno povezana krmilna enota je prirejena za krmiljenje vsakega izmed vsakokrat razpoložljivih električnih prekinjevalnih sklopov v vsakem izmed omenjenih sekundarnih tokokrogov vsakega izmed vsakokrat razpoložljivih svetlobnih virov kot tudi za prekinitev napajanja z električno energijo v primem, če bi bili vsi razpoložljivi sekundami električni tokokrogi kratko stično sklenjeni.In the multifunctional light according to the invention, it is provided that each of the available light sources is electrically connected to a specific, second-only, electrical circuit, in which, in addition to said light source, an electrical interrupting device is also installed, with all circuits available for each second being available. sequentially electrically connected to the primary electrical circuit, which includes a single and all secondary circuits, and therefore all available light sources, a common single-channel DC-DC converter, with which the electrically connected control unit is adapted to control any of the electrical breakers available. of the circuits in each of the said secondary circuits of each of the light sources available, as well as for interruption of the power supply in the event that all the available seconds are short circuited.

Pri eni od možnih izvedb izuma vir električne energije za napajanje primarnega električnega tokokroga in tudi krmilne enote predstavlja enokanalni DC-DC konvertor.In one embodiment of the invention, the power source for powering the primary electrical circuit and also the control units is a single-channel DC-DC converter.

Pri alternativni izvedbi izuma vir električne energije predstavlja krmilna enota, preko katere je električno napajan enokanalni DC-DC konvertor, preko slednjega pa tudi primarni električni tokokrog z integriranimi sekundarnimi tokokrogi.In an alternative embodiment of the invention, the power source is a control unit through which a single-channel DC-DC converter is electrically powered, and through the latter a primary electrical circuit with integrated secondary circuits.

Vsaj en svetlobni vir po izbiri predstavlja žarnica z žarilno nitko in/ali svetleča dioda (LED) in/ali niz med seboj električno povezanih svetlečih diod (LED).At least one light source is optionally represented by a filament lamp and / or a light emitting diode (LED) and / or a set of interconnected light emitting diodes (LEDs).

Nadalje je po izumu predvideno, da vsaj en s pomočjo krmilne enote krmiljen električni prekinjevalni sklop v vsaj enem izmed sekundarnih električnih tokokrogov s pripadajočim svetlobnim virom, predvidenim za izvajanje vnaprej določene svetilne funkcije, predstavlja bodisi mehansko delujoče stikalo ali elektromehansko delujoče stikalo ali pa električni polprevodniški element, po izbiri tranzistor.It is further contemplated according to the invention that at least one controllable electrical disconnecting device in at least one of the secondary electrical circuits with an associated light source intended to perform a predetermined illumination function is either a mechanically operated switch or an electromechanically operated switch, or an electrical semiconductor element, optionally transistor.

Omenjena krmilna enota je v splošnem predvidena za določanje vsakokrat potrebnih svetilnih funkcij vsakokrat razpoložljivih svetlobnih virov, po izbiri pa tudi za določanje jakosti toka na DC-DC konvertorju, ki je potreben za nemoteno izvajanje vsakokrat potrebnih svetilnih funkcij vsakokrat aktivnih svetlobnih virov.Said control unit is generally provided for determining the required lighting functions of the light sources available at each time, and optionally for determining the current intensity on the DC-DC converter, which is necessary for the smooth operation of the lighting functions of the active light sources in question.

Izum bo v nadaljevanju podrobneje obrazložen na osnovi primerov izvedbe ter v povezavi s priloženo skico, kjer kažetaThe invention will now be explained in more detail on the basis of the examples and in connection with the attached sketch showing

Sl. 1 simbolično električno shemo prvega primera izvedbe večfunkcijskega svetila po izumu inFIG. 1 is a symbolic electrical diagram of a first embodiment of a multifunctional light according to the invention and

Sl. 2 simbolično električno shemo drugega primera izvedbe večfunkcij skega svetila po izumu.FIG. 2 is a symbolic electrical diagram of another embodiment of a multifunctional light according to the invention.

Na Sl. 1 je shematično ponazorjeno večfunkcijsko svetilo motornega vozila, ki v tem primeru obsega dva v ustreznem ohišju svetila vgrajena, pred zunanjimi vplivi zaščitena in po izbiri za sodelovanje z vsakokrat razpoložljivim reflektorjem in/ali lečo prirejena svetlobna vira 1, 2. Vsak izmed omenjenih svetlobnih virov 1, 2 je v tem primeru na voljo kot niz svetlečih diod (LED) in je kot tak predviden za izvajanje vnaprej določene svetilne funkcije, in sicer vsakokrat neodvisno od izvajanja svetilne funkcije s strani vsakokrat preostalega svetlobnega vira 1, 2.In FIG. 1 is a schematically illustrated multifunctional motor vehicle light comprising in this case two lamps fitted in a suitable housing, protected from external influences and optionally adapted to the available reflector and / or lens, a light source 1, 2. Each of said light sources 1, 2 is in this case available as a set of light emitting diodes (LEDs) and is intended as such to perform a predetermined illumination function, each time independently of the illumination function performed by the remaining light source 1, 2.

Tako je lahko npr. prvi svetlobni vir 1 prirejen za izvajanje funkcije kratke luči, drugi svetlobni vir 2 pa za izvajanje funkcije smernega kazalca.Thus, e.g. the first light source 1 adapted to perform the dipped beam function and the second light source 2 adapted to perform the direction indicator function.

Kot omenjeno, sta v tem primeru oba svetlobna vira 1, 2 na voljo kot niza svetlečih diod (LED), dasiravno bi bil vsaj eden izmed njiju lahko na voljo bodisi kot ena sama svetleča dioda (LED) ali tudi kot žarnica z žarilno nitko, npr. halogenska žarnica.As mentioned, in this case, both light sources 1, 2 are available as arrays of LEDs, at least one of them could be available either as a single LED or as a filament lamp. e.g. halogen lamp.

Za krmiljenje omenjenih svetilnih funkcij v konkretnem primeru razpoložljivih svetlobnih virov 1, 2 je v splošnem predvidena krmilna enota 4 s pripadajočim DCDC konvertorjem 5, od katere je odvisno napajanje in delovanje vsakega izmed svetlobnih virov 1, 2 v smislu vsakokrat izbranih svetilnih funkcij svetila.In order to control said lighting functions in the specific case of available light sources 1, 2, it is generally provided for a control unit 4 with associated DCDC converter 5, which depends on the power and operation of each of the light sources 1, 2 in terms of the respective luminous lighting functions.

V skladu s predlagano rešitvijo po izumu je vsak izmed omenjenih svetlobnih virov 1, 2 električno povezan v poseben, zgolj njemu lasten sekundami električni tokokrog 100, 200, v katerem je poleg vsakokratnega svetlobnega vira 1, 2 vsakokrat vgrajen tudi električni prekinjevalni sklop 10, 20. Oba razpoložljiva sekundama tokokroga 100, 200 sta zaporedno električno povezana v primarni električni tokokrog 50, v katerem pa je vključen en sam in obema sekundarnima tokokrogoma 100, 200 in torej tudi obema razpoložljivima svetlobnima viroma 1, 2 skupen enokanalni DC-DC-konvertor 5. S slednjim je električno povezana krmilna enota 4, ki je prirejena za krmiljenje vsakega izmed omenjenih električnih prekinjevalnih sklopov 10, 20 v vsakem izmed omenjenih sekundarnih tokokrogov 100, 200 vsakega izmed omenjenih svetlobnih virov 1, 2. Vir električne energije za napajanje primarnega električnega tokokroga 50 in tudi krmilne enote 4 v tem primeru predstavlja enokanalni DC-DC konvertor 5.According to the proposed solution according to the invention, each of said light sources 1, 2 is electrically connected to a specific, second-only, electrical circuit 100, 200, in which, in addition to the respective light source 1, 2, an electrical interrupting circuit 10, 20 is each in each case installed. Both of the available seconds of circuit 100, 200 are connected in series to the primary electrical circuit 50, which includes a single and both secondary circuits 100, 200 and therefore both available light sources 1, 2 common single-channel DC-DC converter 5 The latter is an electrically coupled control unit 4 adapted to control each of said electrical interrupting circuits 10, 20 in each of said secondary circuits 100, 200 of each of said light sources 1, 2. A source of power for supplying the primary electrical circuit 50 and also the control units 4 in this case is a single-channel DC-DC converter 5.

Omenjena krmilna enota 4 je v tem primeru predvidena za določanje vsakokrat potrebnih svetilnih funkcij vsakokrat razpoložljivih svetlobnih virov 1, 2, in sicer s krmiljenjem električnih prekinjevalnih sklopov 10, 20 v sekundarnih tokokrogih 100, 200. Kadar je namreč električni prekinjevalni sklop 10, 20 določenega sekundarnega tokokroga 100, 200 sklenjen, je pripadajoči sekundarni tokokrog 100, 200 v kratkem stiku in tok teče skozi električni prekinjevalni sklop 10, 20 do vsakokrat nadaljnjega sekundarnega tokokroga 100, 200, pri čemer svetlobni vir 1, 2 v tistem sekundarnem tokokrogu 100, 200, kije v kratkem stiku, ne sveti. Pri tem je pomembno poudariti, da tudi v primeru okvare katerega od svetlobnih virov 1, 2 delovanje svetlobnih virov 1, 2 v preostalih sekundarnih tokokrogih 100, 200 poteka nemoteno in popolnoma neodvisno od sekundarnega tokokroga 100, 200 z okvarjenim svetlobnim virom 1,2.Said control unit 4 is in this case intended to determine the necessary lighting functions of the light sources 1, 2 available each time, by controlling the electrical interrupting circuits 10, 20 in the secondary circuits 100, 200. the secondary circuit 100, 200 is closed, the associated secondary circuit 100, 200 is short circuited and the current flows through the electrical interrupting circuit 10, 20 to each further secondary circuit 100, 200, wherein the light source 1, 2 in that secondary circuit 100, 200 , which in short circuit, does not light. It is important to emphasize that even in the event of a failure of one of the light sources 1, 2, the operation of the light sources 1, 2 in the remaining secondary circuits 100, 200 is smooth and completely independent of the secondary circuit 100, 200 with the defective light source 1,2.

Primarni tokokrog 50 je torej v splošnem permanentno napajan z električno energijo preko enega samega DC-DC konverterja 5, vsakokratno svetilno funkcijo določenega svetlobnega vira 1, 2 pa se vrši z razklenitvijo električnega prekinjevalnega sklopa 10, 20 v zadevnem tokokrogu 100, 200, s čimer tok steče v zadevni sekundami tokokrog 100, 200 z integriranim svetlobnim virom 1, 2, ki vrši omenjeno funkcijo. Če je npr. svetlobni vir 1 predviden za izvajanje svetilne funkcije kratke luči, bo ves čas delovanja svetlobnega vira 1 električni prekinjevalni element 10 razklenjen, in bo tok tekel skozi sekundami tokokrog 100 in svetlobni vir 1 naprej proti preostalemu sekundarnemu tokokrogu 200. Če je svetlobni vir 2 v funkciji smernega kazalca, se prekinitve v območju električnega prekinjevalnega elementa 20 vršijo v ritmu delovanja smernega kazalca, pri čemer je krmilna enota 4 je med drugim prirejena tudi za prekinitev napajanja z električno energijo v primeru, kadar sta oba sekundama električna tokokroga 100, 200 kratkostično sklenjena.The primary circuit 50 is thus generally permanently powered by a single DC-DC converter 5, and the respective luminous function of a particular light source 1, 2 is performed by decoupling the electrical interrupting circuit 10, 20 in the circuit 100, 200, thereby the current flows in the relevant seconds of circuit 100, 200 with an integrated light source 1, 2 that performs the said function. If, for example, the light source 1 intended to perform the dipped beam function will be unlocked throughout the operation of the light source 1 and the current will flow through seconds of circuit 100 and the light source 1 forward toward the remaining secondary circuit 200. If light source 2 is in operation of the direction indicator, interruptions in the area of the electrical interrupting element 20 are made in the rhythm of operation of the direction indicator, the control unit 4 being adapted, inter alia, to interrupt the power supply in the event that the two electrical circuits 100, 200 are short-circuited.

Nadalje je na Sl. 2 prav tako shematično ponazorjeno večfunkcijsko svetilo motornega vozila, ki pa v tem primeru obsega tri v ustreznem ohišju svetila vgrajene, pred zunanjimi vplivi zaščitene in po izbiri za sodelovanje z vsakokrat razpoložljivim reflektorjem in/ali lečo prirejene svetlobne vire 1, 2, 3. Svetlobni vir 2 predstavlja dioda (LED), preostala dva svetlobna vira 1 in 3 pa sta vsak zase izvedena kot niz diod (LED).Furthermore, in FIG. 2 also shows a schematically illustrated multifunctional motor vehicle light, which in this case comprises three lamps fitted in an appropriate housing, protected from external influences and optionally for co-operating with the available reflector and / or lens of the adapted light source 1, 2, 3. source 2 is a diode (LED), and the remaining two light sources 1 and 3 are each individually designed as a series of diodes (LEDs).

Vir električne energije v tem primeru predstavlja krmilna enota 4, preko katere je električno napajan enokanalni DC-DC konvertor 5, s tem pa tudi primarni električni tokokrog 50 z integriranimi sekundarnimi tokokrogi 100, 200, 300.In this case, the power source is the control unit 4 through which the single-channel DC-DC converter 5 is electrically powered, and thus also the primary electrical circuit 50 with integrated secondary circuits 100, 200, 300.

Delovanje omenjenega primarnega tokokroga 50 in sekundarnih tokokrogov 100, 200, 300 v smislu izvajanja svetilnih funkcij posameznih svetlobnih virov 1, 2, 3 tudi v tem primeru poteka povsem analogno kot v predhodno opisanem primeru po Sl. 1.The operation of said primary circuit 50 and secondary circuits 100, 200, 300 in the sense of performing the luminous functions of individual light sources 1, 2, 3 also in this case proceeds in a completely analogous fashion to that described in FIG. 1.

Krmilna enota 4 je po izbiri lahko predvidena za določanje vsakokrat potrebnih svetilnih funkcij vsakokrat razpoložljivih svetlobnih virov 1, 2, 3 in obenem tudi za določanje jakosti toka DC-DC konvertorju 5, ki je potreben za nemoteno izvajanje vsakokrat potrebnih svetilnih funkcij vsakokrat aktivnih svetlobnih virov 1, 2, 3. Razen tega pa je krmilna enota 4 prirejena za prekinitev oskrbe primarnega tokokroga 50 z električno energijo v primeru nedovoljenega stanja, kadar so vsi razpoložljivi sekundami tokokrogi 100, 200, 300 vsak zase kratkostično sklenjeni.Control unit 4 can optionally be provided to determine the required lighting functions of the available light sources 1, 2, 3 at the same time, and also to determine the current intensity of the DC-DC converter 5, which is required for the smooth execution of the necessary lighting functions of the active light sources at each time. 1, 2, 3. In addition, control unit 4 is adapted to interrupt the supply of primary circuit 50 with electricity in the event of an unauthorized condition when all available seconds of circuits 100, 200, 300 are each short-circuited.
